ELK Studios
ELK Studios Slots: Pirots, Cygnus and Nitropolis
ELK Studios is a Swedish slot studio with one habit that sets it apart: when a game works, it builds a series around it and reworks the mechanics each time. At Slots99 that means the Pirots, Cygnus, Nitropolis and Toro series sit side by side with a deep back catalogue of one-off titles. Most of them are medium-high volatility, and every one is a video slot you can open in a free demo before you stake a cent.
This page answers the three things you came for: which ELK Studios games we carry, what the studio is known for, and how to try one free and then play it properly. Slots99 is for players aged 18 or over.
The ELK Studios games in our lobby
The game grid on this page is the full list of ELK Studios titles we carry, and it follows our live catalogue, so it changes as the studio releases new games. If you searched for an "ELK Studios games list", this is it. The headline series are Pirots, Cygnus, Nitropolis and the Toro titles, each with sequels covered in the sections below.
Around those series sits the back catalogue: the Gold family, from Avalon Gold to Zulu Gold, sequels such as Tropicool 2, Heist Guys 2 and Ice Wolf 2, and one-offs such as Propaganda, Bompers and Illogicool. We do not carry every game ELK has ever made, so if a title is not in the grid, it is not in our lobby.
What ELK Studios is known for
Four habits define the studio and shape what you will find here.
Mobile first. ELK has long described its approach as mobile first: games are designed for a phone screen and then scaled up, not the other way round. That is why the reels, buttons and information panels in an ELK slot read cleanly on a small screen.
Mechanics that get reworked. A sequel keeps the theme and the core idea, then changes the grid, the features or the maths. The volatility section further down shows sequels moving in both directions.
A distinctive look. Bold cartoon art, a sense of humour and recurring characters run through the catalogue. Toro the bull is the most familiar face, but the same humour shows up in titles like Gritty Kitty and Taco Brothers.
Medium-high maths. Most ELK titles we carry are medium-high volatility, so they tend to save their best moments for the feature round. That shapes how you should try them.
Try any ELK Studios slot free in demo mode
Free play is what a lot of Canadian players look for first, and ELK suits it well. Every ELK title here is a slot, not a live table, and each one opens in a free demo: no account, no deposit. The demo runs the same game with the same maths as the real-money version, only with play credits instead of your balance.
Demo mode is the honest way to learn an ELK game, because ELK features take time to show up. On a medium-high volatility slot the bonus round can stay away for a long stretch. Give a demo a hundred spins or more and you will know whether its rhythm suits you. What demo play can and cannot show you is covered on our all slots page.
How to play ELK Studios slots, step by step
Every ELK game here starts the same way, but each plays differently once the reels load. These steps take you from this page to a real-money spin.
- Pick a starting point. If a series catches your eye, open its first game, such as Pirots, Cygnus or Nitropolis. Sequels build on the original idea, so the first game is the easiest way in.
- Open it in demo. Start the game in demo mode from its page. You do not need an account for this step.
- Read the rules panel before you spin. Every ELK game has an information panel with the paytable, the feature rules and the game's return figure. ELK reworks its mechanics between instalments, so read it fresh in every game, sequels included.
- Set a stake and a session length. Choose a stake you would be comfortable repeating many times, and decide how many spins you will play before you stop and check the balance.
- Watch for the feature. In most ELK slots the feature round is where the game shows its character. Note how often it arrives in demo and what it does when it lands.
- Switch to real money only if you want to. Create an account, make a deposit and open the same game. Nothing about the maths changes.
- Set your limits first. Our responsible gaming page explains the limits you can set. Do it before your first real spin, not after a bad session.
Stakes, autoplay and bet strategies
Each ELK slot sets its own stake range, and you change your stake from the game's stake control. Some ELK titles also offer preset bet strategies inside autoplay, which raise or lower your stake automatically after wins or losses. They are optional. A strategy that raises your stake after a loss is chasing losses on a timer, so keep autoplay on a flat stake you chose yourself.
If you are playing with a welcome bonus, the maximum bet while wagering is $5 per spin. If your usual ELK stake is higher, lower it before the session starts rather than halfway through.
Pirots: ELK's gem-collecting series
Pirots shows what ELK does with a grid. In the original, a crew of colourful cartoon birds moves around the board collecting gems, collected symbols clear away for new ones, and the playing area can grow as a round goes on. Each sequel reworks that formula rather than repeating it.
We carry Pirots, Pirots 2, Pirots 4 and Pirots 5. Pirots, Pirots 4 and Pirots 5 all sit at medium-high volatility. Start with the original in demo, then open a later one and see how differently the board plays.
Cygnus and ELK's space slots
Cygnus is ELK's space series, and its sequels stay in deep space. We carry Cygnus, Cygnus 2, Cygnus 3, Cygnus 4 and the sixth game in the series. Cygnus, Cygnus 2 and the sixth instalment are medium-high games. Each instalment changes how its reels and features behave, so treat every one as a new game.
Io and Stars Of Orion are in the grid as well. For space slots from every studio we carry, our cosmic collection gathers them by theme.
Nitropolis
Nitropolis moves ELK into a neon, futuristic city. Every instalment we carry shares the same volatility: Nitropolis,Nitropolis 2, Nitropolis 3 and Nitropolis 4 are all medium-high. The games are busy, with a large reel area and plenty happening on each spin.
The Toro family
Toro is a cartoon bull who keeps coming back. Wild Toro is set in the bullring, where the bull walks across the reels as a wild, and Wild Toro 2 builds on that idea. He also stars in GladiaToro, Toro Shogun and Buffalo Toro.
Book of Toro puts him in the familiar book format, and Toro 7s nods to the lucky sevens of older slot machines. Book of Toro, Buffalo Toro, Toro Shogun, Toro 7s and Wild Toro 2 are medium-high volatility titles.
The Gold titles, the X titles and Coba
A long run of ELK titles carries "Gold" in the name, each set somewhere different: Avalon Gold, Katmandu Gold, Valhall Gold, Zulu Gold, Tahiti Gold and Pacific Gold. Ecuador Gold, Black River Gold, Dead Man's Gold and Voodoo Gold round out the family.
Avalon and Katmandu each appear twice, once as a Gold title and once as an X title, and they are not the same ride. Avalon X is medium volatility, against medium-high for Avalon Gold. Katmandu X goes the other way: high, against medium-high for Katmandu Gold. Coba and its remake Coba Reborn tell the same story, with the original at medium and the remake at high. Same setting, different ride: that is why ELK sequels are worth trying in demo first.
More sequels and one-offs in the back catalogue
Beyond the big series, ELK keeps returning to its own ideas. Tropicool, Tropicool 2 and Tropicool 5 are each medium-high. Heist Guys is a medium game and Heist Guys 2 a medium-high one. Ice Wolf is high volatility, while Ice Wolf 2 drops a step to medium-high. Phoenix Graveyard continues in Phoenix Graveyard II, and Taco Brothers in Taco Brothers Derailed.
Then come the one-offs: Blood Lust, Diablo Reels, Deadcode, Dam Beavers, Giraffalot, Bonzo's Bananza, Micro Knights, Crusader, Cluster Slide, Dropz and Freeway 7. Ashoka, Sumo Sumo and J-Pop look to Asia, and our Asian collection has more in that vein from other studios. Book of Sam gives ELK's other recurring character a book-style game, and Arcanum and Cathedral 9 wait in the grid too.
ELK Studios volatility at a glance
ELK's catalogue leans one way. Most of the titles we carry are medium-high: expect quieter stretches between wins of note, with much of a game's value packed into its feature round. A handful sit on either side of that, and they are worth knowing by name.
High volatility: Coba Reborn, Hit It Hard, Ice Wolf, Katmandu X and Valhall Gold.
Medium volatility: Avalon X, Coba, Fish and Bird, Heist Guys and World Eaters.
Notice how often a sequel or remake lands at a different level from its original. For a calmer session, start with the medium titles in demo; for a swingier one, try the high ones. How volatility works in general is explained on our all slots page.
ELK Studios slots on mobile and mobile data
Mobile first is ELK's own description of how it builds games, and it shows on a phone. ELK games open in your mobile browser at Slots99 and the controls are made for touch. Demo mode works on mobile exactly as it does on a desktop.
If you play in South Africa on mobile data, two habits help. Load a new ELK game on Wi-Fi the first time you open it, because the opening load carries the artwork and sound and is the heaviest part of the session; individual spins use far less. And if your signal is weak, mute the sound and close other tabs so the game has the connection to itself.

ELK Studios beside the other studios we carry
Searches for ELK Studios often sit next to searches for other studios. If yours started with Pragmatic Play or Hacksaw Gaming, both have their own pages here: Pragmatic Play slots and Hacksaw Gaming games. Relax Gaming and Big Time Gaming have pages too. Each studio page lists only that studio's games, the same way this one lists only ELK's.

ELK Studios slots: frequently asked questions
Which ELK Studios games can I play at Slots99?
Every ELK title in the grid on this page: the Pirots, Cygnus, Nitropolis and Toro series, the Gold and X titles, and a long back catalogue of sequels and one-offs. The grid follows our live catalogue, so if an ELK game is not in it, we do not carry it.
Can I play ELK Studios slots for free?
Yes. Every ELK title here is a slot, and each one opens in a free demo with no account and no deposit. The maths are the same as in the real-money version.
What is ELK Studios known for?
ELK Studios is a Swedish studio known for building games mobile first, for series that get reworked with each instalment, and for bold cartoon art with characters such as Toro the bull.
What kinds of slots does ELK Studios make?
Grid games where characters collect symbols, as in Pirots, and reel games with a walking wild, as in Wild Toro. There are also book-format games such as Book of Sam and Book of Toro, and titles that nod to classic sevens, such as Toro 7s.
Does Slots99 rank ELK slots by payout?
No. Each ELK game shows its return figure in its information panel, but that figure is a long-run average over a vast number of spins and says nothing about your session. We do not rank or compare ELK titles on it. Choose by theme, mechanic and recorded volatility, and try the game in demo first.
Is Slots99 a licensed casino site?
Yes. Slots99 is operated by Disrupt Entertainment Limited N.V., registration number 140327, and holds licence number OGL/224/668/0844. Check the operator and licence on any site before you deposit, and read the terms and conditions.
Is there an ELK Studios promotion code?
No. Studios do not issue promotion codes for our lobby, and any "ELK Studios code" for Slots99 you see elsewhere is not ours. Our current offers, and how to claim them, are on the promotions page.
Do ELK Studios slots work on mobile?
Yes. ELK designs its games for the phone first, and they open in your mobile browser in demo or for real money.
Which ELK Studios game should I try first?
We do not publish a popularity chart for ELK, in South Africa, Canada or anywhere else. A good signal is the series ELK itself keeps returning to: Pirots, Cygnus, Nitropolis and the Toro titles. Start with the first game of whichever appeals and play it in demo.
Are there ELK Studios table games or live tables?
No. Every ELK title in our lobby is a video slot. If you want the other common casino games, blackjack and roulette are played live in our live casino, which runs 350+ tables from other studios.
Play ELK Studios slots responsibly
ELK's medium-high maths means long quiet stretches are normal, and that is exactly when it is easiest to stake more than you meant to. Treat every session as entertainment you can afford to lose: never as income, and never as a way to win back a loss. Set a budget before you open the game, keep autoplay on a flat stake, and stop when the budget is gone. If gambling stops being fun, our responsible gaming page explains the tools we offer and where to find support.
